Seafoam questions and concerns

ur o2 will be fine, i think ive done sea foam 3-4 times and i just got a good look at my upstram o2 and it looked normal. since u wanna clean ur throttle body good, start car and remove vacume hose from crankcase and suck down a good 1/3 bottle at least (while car is runnin).

I've used about 10 cans of seafoam total on several different cars. All of them I sucked up about a 1/3 of the bottle through a vacuum hose while someone sat in the car and reved it just enough so it wouldn't stall. After that I let the vacuum suck up another 1/3 of the bottle as quickly as possible then killed the engine and waited 5mins to an hour. Never done harm yet and my forenza will blow out tons of smoke for 20+ mins at ~3k RPM.

Do you attribute the smoke that comes out the exhaust to the deposits being burned, or the sea foam itself being burned?

What kittyllama said is my reply, but also don't forget after waiting about 10 minutes with the engine off, turn it back on and run it for about 10-20 mins to get the last of the seafoam and carbon out, otherwise if you don't it'll just get stuck back on the engine parts.

The smoke that comes out is both, but mostly carbon. My mom's car has like 125k miles on it, mine has about 48k, when I did both of the cars they both spewed smoke, but my mom's car had mabye 2-3x more than mine, it got so bad that one of my neighbors almost called the fire department cause there was so much smoke.

The bottom line is though if you see white smoke, it's a good thing. The vaccuum hose is the best way to put it in the engine, and I don't really know about the O2 sensor, but if you put it in the Aveo's vaccuum line it won't affect it (unless mabye the smoke gets sucked into the intake or something ;D)

do i need a second person or can I just do a 1/3 of the bottle then shut the car off?

Yeah thats what I have done before kinkyllama.

Sam: You could do it yourself if you can find a way to hold the hose in the can and slightly pull the throttle. But easiest way is to have a friend

I think I pour some of the seaform in a container and pull the throttle.....that way it doesnt suck down the whole bottle lol

WAY late responding here... how about pour the other 2/3 into your tank first, then you wont have to worry about a seperate container or sucking out too much ;)

not late at all...still havent got around to doing it :lol:
